The International Journal of Signs and Semiotic Systems (IJSSS) combines interdisciplinary approaches on theoretical, empirical, formal, and computational research that contributes to the design and synthesis of semiotic systems, including biological evidence and evolutionary and philosophical frameworks. This journal publishes original research on the design, analysis, and synthesis of semiotic processes in biological and artificial systems and encompasses technological applications on computational modeling of semiotic production, computing, interpretation, and communication. Articles included in this publication present comparative approaches to semiotic processes including evolutionary, synthetic and analytic perspectives.
